1966 Sunbeam Tiger Mark IA Sport Roadster

It is believed that 1,826 MkIAs were produced with the 206 cubic-inch Ford small-block V8 - described by Ford as the world's lightest cast iron V8 - with a quoted 164 horsepower at 4400RPM and 258 lb-ft of torque at 2300 RPM, and a 4-speed gearbox. This car has a major but virtually invisible upgrade, a replacement 5-speed is installed that can indeed help the driver us more of the available performance. Rootes Group never offered a 5-speed. An automatic transmission was installed on several prototypes but was never offered to the public; there's no record that a 5-speed prototype ever existed.
